Embodiment
Please refer to Fig. 1 to shown in Figure 4, fuel pump of the present invention includes the shell 14 that is provided with rotor chamber 10, refluxing chamber 4 and emulsifying chamber 1, be fixed in magnetic pole of the stator 5 on the shell 14, be installed on rotor chamber 10 interior rotors 6, be arranged at the filler opening of shell 14 upper ends, the water intake that is arranged at refluxing chamber 4 one sides, the oil outlet 27 that is connected with shell 14 and by motor-driven impeller 2, impeller 2 is installed in the emulsifying chamber 1 and is fixed on the main shaft of rotor 6, and is fixing by axle sleeve 24.Wherein electric machine main shaft extend in the emulsifying chamber 1 after passing refluxing chamber 4, is connected with oil inlet pipe 7 on the filler opening, is connected with intake pipe 3 on the water intake 3.
During the internal-combustion engine normal operation, 2 rotations of motor driving impeller, liquid in the emulsifying chamber 1 since under the effect of centrifugal force near main shaft the generation negative pressure, under the driving of pressure reduction, fuel oil in the fuel tank 18 enters rotor chamber 10 through oil inlet pipe 7, rotor 6 obtains Cooling and Lubricator, fuel oil enters refluxing chamber 4 again, water in the water tank 17 enters refluxing chamber through intake pipe simultaneously, profit enters emulsifying chamber 1 simultaneously, the impeller 2 of High Rotation Speed drives the oil water mixture rotation, oil water mixture rotates around electric machine main shaft, is subjected to centrifugal action peripolesis of 1 towards the emulsifying chamber, in this process, because the angular velocity of rotation of oil water mixture is less than impeller 2 angular velocity, during through hole 26 on mixture is flowed through impeller 2 blades, will pass through hole 26 and enter another one leaf district 16, the stirring of impeller 2 and oil water mixture different leaves district 2 connect shuttle back and forth and make oil water mixture obtain emulsification and supercharging, enter oil sprayer 19 from shell 14 oil emulsion out by pipeline, realized emulsification limit, the limit burning of fuel oil.Loine pressure rising Decompression valves 13 will be opened when the oil emulsion oil feed line occurs to stop up, and oil emulsion will circulate between refluxing chamber 4 and emulsifying chamber 1 by relief tube 20 and oil outlet tube 23, and motor just can not be overheated because of overload.During engine start, at first open fuel pump more than 30 seconds, the oil water mixture of layering can pass through oil nozzle 19, return tube 15 and return opening 29 and enters in the refluxing chamber 4 in the pipeline, prevents that the parking period fuel layering from affecting the startup of motor.When the fuel delivery of fuel pump surpassed the fuel injection quantity of oil spout oil nozzle 19, oil emulsion also can circulate again through entering refluxing chamber 4 through reflow pipe 15.In order to obtain better emulsifying effectiveness, the fuel delivery of design fuel pump makes repeatedly circulating emulsion of oil emulsion greater than the fuel injection quantity of oil nozzle 19.
Fuel pump among the present invention is by the motor driving wheel rotation, and the through hole that arranges on the stirring of impeller and the blade makes profit obtain emulsification, have simple in structure, volume is little, emulsify well, emulsifying rate fast, be convenient to the advantage installed and used at vehicle.
More than; describe the preferred embodiments of the present invention in detail, but the claimed interest field of the present invention is not limited to this, has utilized basic conception of the present invention; various distortion and improvement that the person of ordinary skill in the field carries out still belong to the interest field of request of the present invention.
